Abstract

A self-sealing tire according to the present invention includes a pneumatic tire and a puncture sealing layer disposed over a whole tire inner wall surface from one shoulder portion to the other shoulder portion of the pneumatic tire.

The puncture sealing layer comprises an annular sponge layer which is impregnated with an adhesive so as to be exposed on a radially outer surface side thereof, and a bonding layer of an adhesive which is provided on a radially outer surface of the sponge layer and is adhered to the tire inner wall surface.
The sponge layer is provided in a compressed state. The puncture sealing layer is press attached to the tire inner wall surface by a recovery force of the compressed sponge layer.

Claims (13)

1. A self-sealing tire having a pneumatic tire and a puncture sealing layer disposed over a whole tire inner wall surface from one shoulder portion to the other shoulder portion of the pneumatic tire, wherein the puncture sealing layer comprises an annular sponge layer which is impregnated with an adhesive so as to be exposed on a radially outer surface side thereof, and a bonding layer of an adhesive which is provided on a radially outer surface of the sponge layer and is adhered to the tire inner wall surface, the sponge layer being provided in a compressed state, the puncture sealing layer being press attached to the tire inner wall surface by a recovery force of the compressed sponge layer.
2. The self-sealing tire of claim 1, wherein a relationship between an outer circumference length Ls of the sponge layer at a position corresponding to that of the tire centerline of the pneumatic tire prior to attachment of the puncture sealing layer and a tire inner circumference length Lt of the tire inner wall surface at a position of the tire centerline is set to 1.1 Lt <= Ls<=1.3 Lt.
3. The self-sealing tire of claim 1 or 2, wherein the bonding layer is made of the same adherent composition as the adhesive with which the sponge layer is impregnated.
4. The self-sealing tire of claim 3, wherein said bonding layer is integrally formed on the radially outer surface of the sponge layer.
5. The self-sealing tire of claim 1, 2, 3 or 4, wherein the thickness of the sponge layer prior to attachment of the puncture sealing layer is 5 to 15 mm.
6. The self-sealing tire of claim 5, wherein the impregnation depth of the adhesive which is impregnated into the sponge layer prior to attachment of the puncture sealing layer is 4 to 12 mm.
7. The self-sealing tire of any one of claims 1 to 6, wherein the adhesives are made of an adherent composition not containing solvent.
8. A method of manufacturing a self-sealing tire having a pneumatic tire and a puncture sealing layer disposed over a whole tire inner wall surface from one shoulder portion to the other shoulder portion of the pneumatic tire, comprising the steps of:

impregnating an annular sponge layer with an adhesive from a radially outer surface side thereof to form an adhesive impregnated sponge layer so that the adhesive is exposed on the radially outer surface side;

forming a bonding layer made of an adhesive on a radially outer surface of the adhesive impregnated sponge layer to form a puncture sealing layer; and press attaching the puncture sealing layer onto the tire inner wall surface via the bonding layer by a recovery force of the sponge layer which has compressed.
9. The self-sealing tire manufacturing method of claim 8, wherein a relationship between an outer circumference length Ls of the sponge layer at a position corresponding to that of the tire centerline of the pneumatic tire prior to attachment of the puncture sealing layer and a tire inner circumference length Lt of the tire inner wall surface at a position of the tire centerline is set to 1.1 Lt <=
Ls<=1.3 Lt.
10. The self-sealing tire manufacturing method of claim 8 or 9, wherein the adhesives are made of an adherent composition not containing solvent.
11. A method of manufacturing a self-sealing tire having a pneumatic tire and a puncture sealing layer disposed over a whole tire inner wall surface from one shoulder portion to the other shoulder portion of the pneumatic tire, comprising the steps of:

impregnating an annular sponge layer with an adhesive from a radially outer surface side thereof to form an adhesive impregnated sponge layer so that the adhesive is exposed on the radially outer surface side, and to simultaneously form a bonding layer made of the adhesive on a radially outer surface of the adhesive impregnated sponge layer integrally therewith, thereby forming a puncture sealing layer; and press attaching the puncture sealing layer onto the tire inner wall surface via the bonding layer by a recovery force of the sponge layer which has compressed.
12. The self-sealing tire manufacturing method of claim 11, wherein a relationship between an outer circumference length Ls of the sponge layer at a position corresponding to that of the tire centerline of the pneumatic tire prior to attachment of the puncture sealing layer and a tire inner circumference length Lt of the tire inner wall surface at a position of the tire centerline is set to 1.1 Lt <=
<= 1.3 Lt.
13. The self-sealing tire manufacturing method of claim 11 or 12, wherein the adhesive is made of an adherent composition not containing solvent.
